We look at the division of 49309479 by 452 
The aim is to understand the frequency of 452 in 49309479.

On to step 1:
452 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 452

Step 2:
If we divide 49 by 452, we get 0 and a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 452

Advancing to step 3:
When dividing 493 by 452, we get 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 452 from 493 to get 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 452

On to step 4:
If we divide 410 by 452, we get 0 and a remainder of 410.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 410, we get 410.
Grab the next digit (9) from the dividend, add it to 410, then carry on: 4109 / 452

Going ahead to step 5:
When dividing 4109 by 452, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 109.0
Deduct 4068 from 4109 and we're left with 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 452

Moving on to step 6:
The number 452 fits into 414 0 times, leaving a remainder of 414.
The number 0 becomes the next digit in our result. 
Result so far: 1090.0
The remainder is 414 after subtracting 0 from 414.
Take the next digit (7) from the dividend and append it to 414, then repeat: 4147 / 452

On to step 7:
When dividing 4147 by 452, we get 9 with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 10909.0
If we subtract 4068 from 4147, we get 79.
Grab the next digit (9) from the dividend, add it to 79, then carry on: 799 / 452

Advancing to step 8:
452 can be fit into 799 1 times, resulting in a remainder of 347.
Record the quotient 1 as the next digit in the result. 
Result so far: 109091.0
The remainder is 347 after subtracting 452 from 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 9:
When dividing 3470 by 452, we get 7 with a remainder of 306.
Use 7 as the next digit of our solution. 
Result so far: 109091.7
If we take 3164 away from 3470, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 10:
3060 divided by 452 is 6 with a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 109091.76
Subtracting 2712 from 3060 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 11:
When dividing 3480 by 452, we get 7 with a remainder of 316.
Use 7 as the next digit of our solution. 
Result so far: 109091.767
If we subtract 3164 from 3480, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 12:
452 can be fit into 3160 6 times, resulting in a remainder of 448.
The number 6 becomes the next digit in our result. 
Result so far: 109091.7676
If we subtract 2712 from 3160, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 13:
452 can be fit into 4480 9 times, resulting in a remainder of 412.
Use 9 as the next digit of our solution. 
Result so far: 109091.76769
If we take 4068 away from 4480, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 14:
4120 divided by 452 is 9 with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 109091.767699
Deduct 4068 from 4120 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 109091.767699 with a remainder of 5.2e-06.
